What is Incoloy 800H?

Incoloy 800H is a nickel-iron-chromium alloy that belongs to the class of superalloys. This alloy is derived from Incoloy 800, with the letter ‘H’ signifying the modification that distinguishes it. The primary modification in 1.4958 / 1.4876 alloy is its higher carbon content (0.05-0.10%), which enhances its high-temperature strength and resistance to oxidation, carburization, and sulfidation. This makes it a valuable material for applications involving elevated temperatures and aggressive environments.

Key Properties of Incoloy 800H

• High-Temperature Resistance: Incoloy 800H excels in environments where temperatures can soar to 1100°C (2000°F) and beyond. It retains its structural integrity and mechanical properties even at extreme temperatures, making it ideal for furnace components and heat exchangers.
• Corrosion Resistance: The alloy exhibits excellent resistance to oxidation, carburization, and sulfidation, making it suitable for applications in chemical processing, petrochemical, and power generation industries.
• Creep and Rupture Strength: N08810 alloy maintains its mechanical strength over extended periods, offering superior resistance to creep and rupture at high temperatures. This property is invaluable in applications involving sustained stress, such as pressure vessels and power plant components.
• High Thermal Stability: The alloy’s ability to maintain its properties at elevated temperatures makes it an excellent choice for applications requiring long-term thermal stability.

Benefits of Incoloy 800H

• Longevity: Its resistance to high-temperature degradation and corrosion ensures a longer service life in challenging environments.
• Versatility: The alloy’s wide range of applications across various industries showcases its versatility.
• Low Maintenance: Incoloy 800H components often require less maintenance due to their robust nature.
• Cost-Effective: While it may have a higher initial cost, the longer lifespan and lower maintenance requirements make it a cost-effective choice in the long run.
